Algunos aspectos biológicos de los hongos micorrícicos arbusculares (AMF)

The ecological mechanisms by which plant diversity (species richness and composition ) is regulated and maintained are not well understood; so far, little attention has been paid to the effects of soil microbe-plant interactions, particularly mycorrhizal symbiosis. Hence, the aim of t his paper is to review scientific literature relevant to arbuscular mycorrhizal fungi (AMF) biological aspects and the ecological mechanis1ns by which p ant diversity is affected by AM fungal performance . Several studies show up that plant fitness, plant relative growth and abundance, and species competitive balance are affected by AMF. Therefore, AMF are one of the factors that determine plant diversity, and plant community structure . Discussion emphasizes on controversial aspects of AMF-plant diversity research.
